METAL WINIJOW.

Application filed October 14, 1927. Serial 1%. 226,197, a

This invention pertains to window construction as applied to metal widows.

One of the objects of this invention is to provide improved construction for the meeting rails, which will insure a close joint between the same to prevent the air passing through.

Another object is to provide an improved construction whichfwill add to the strength and rigidity of the meeting rail.

Another object is to provide a simple and improved construction for applying a resilient metal Weatherstrip to the meeting rail joint. p

Further objects will appear from the following description, in whiche Figure 1 is an outside view of a metal Window embodying this invention; and

Figure 2 is an enlarged section on line 2 2 of Figure 1. Q

Referring to the drawing, the window embodies a frame 1 having an upper sash 2 and a lower sash 3.

The meeting rail of the lower sash is con structed oftwOparts. The outer member is formed of a sheet of metal, the lower edge of which forms a downwardly extending flange 4. Above the flange 4 the sheet is bent outwardly, as indicated at 5, and then upwardly for a certain distance, after which itis bent backupon itself, so as to form a vertical flange, having an upward extension 6 and a downward extension '7.

, The portions 4, 5 and 7 of this element form an inverted pocket running along the outside of the meeting raiL The other element of this rail comprises asheet of metal having a vertical portion 8 forming a facing for theinside of thelower sash. The sheet isthen bent outwardly, as shown at 9, and downwardly to form a flange 10. The two elements are clamped togetherby a series of screws 11, threaded into the flange 6, or other suitable tastenings. hen so clamped, the flange 10 bears against the upper extension 6 of the outer member, and the portions 4 and 8 engage the window pane 12 so as to secure the same therebetween. 7

The meeting rail of the upper sash may also be formed of two members. Theinner member is bent to a Z-shape, as shown in Fi ure 2. The outer member has a vertical facing portion 1 1 and is bent inwardly The upstanding flange 16 is spaced so as to enter the pocket formedby the portions 4, 5 and 7, thus forming av circuitous path by which drafts must proceed in order to enter the meeting rails. l

In order to effectively close the passage for air drafts between the meeting rails,

a resilient strip of metal 17 is secured to the outer flange 7. The upper portion of the strip 171s turned over the top edge ot'the upper flange 6 and is clamped by the flange vent drafts from entering at this point. It

will be noted that the position of the portion 18 is such that if astrong wind should blow against the outside of-the window so as to build up a pressure tending to force air through the passage therein, such pressure will be exerted against the upper surface of the flange 18 and will tend to force it more firmly into contact with the flange 16 and, therefore, provide a more effective seal. There is thus'no possibility for a strong wind opening the seal by building up an excessive, pressure. i

It willbe seen that this invention provides a simple and effective construction for the meeting rails of metal windows, and one in which an effective Weatherstrip may be applied in a simple and economical manner. The Weatherstrip 17 may be supplied with the windowas a part of its regular equipment. It will also be noted that the rear member of the meeting rail, including the flanges 4, 5 and 7, is in the form of a channel so as to have great strength and stiffness." The upstanding flange 6, to gether with the flanges 4 and 7, also increases the rigidity of the structure, especially during the glazing of the window when the inside facing 8 is removed: WVhen the facing 8 is clamped inplace, the whole rail is given a box section which is very strong. I 7

It is obvious that various changes may-be made, within the scope of the appended claims, in the details of construction withhen so engaged,

out departing from the spirit of this invention; it is, therefore, to be understood that this invention is not limited to the specific details described and shown.

Having thus described the invention, what is claimed ,is:

1. In a metal window having an upper and a lower sash, an upper rail on the lower sash having an upwardly extending flange spaced outwardly from the outer face of the sash, 21 facing for said rail having a flange and clamped against said upwardly extending flange, and a flexible weather strip clamped against said upwardly extending flange.

2. In a metal window having an upper and a. lower sash, an upper rail on the lower sash having an upwardly extending flange spaced outwardly from the outer face of the sash, a facing for said rail having a flange and clamped against said upwardly extending flange, and a flexible weather strip clamped against said upwardly extending flange and extending downwardly therefrom.

3. In a metal window having an upper and a. lower sash, an upper rail on the lower sash having an upwardly extending flange spaced outwardly from the outer face of the sash, a facing for said rail having a flange and clamped against said upwardly extending flange, and a flexible weather strip clamped between said facing and said upwardly extending flange.

4. In a metal window having an upper and a lower sash, an upper rail on the lower sash having an upwardly extending flange spaced outwardly from the outer face of the sash,- a facing for said rail having a flange and clamped against said upwardly extending flange, a flexible weather strip clamped against said upwardly extending flange, and a flange on the lower rail of the upper sash adapted to engage said flexible strip.

5. In a metal window having an upper and a lower sash, an upper rail on the lower sash having an upwardly and downwardly extending flange spaced outwardly from its sash, a lower rail for the upper sash having an upwardly extending flange spaced inwardly from its sash and inwardly of said first flange, and a flexible weather strip clamped to said first flange and engaging said second flange.

6. In a metal window having an upper and a lower sash, an upper rail on the lower sash having an upwardly and downwardly extending flange spaced outwardly from its sash, a lower rail for the upper sash having an upwardly extending flange spaced inwardly from its sash and inwardly of said first flange, a flexible weather strip on said first flange and engaging said second flange,

and a facing for said upper rail adapted to clamp said strip to said first flange.

7. In a metal window having an upper and alower sash, a meeting rail member on the outer face of the lower sash forming the inner wall of a pocket and being then bent outwardly to form the upper wall of said pocket and then upwardly and back upon itself and ending in a downward extension forming the outer wall of said pocket, an inner facing member attached to said meeting rail member and cooperating therewith to secure a pane of glass, and a meeting rail member on the upper sash having a flange adapted to extend into said pocket when the window is closed.

8. In a metal window having an upper and a lower sash, a meeting rail member on the outer face of the lower sash formed of sheet metal by bending the same back upon itself and then separating the edges to form a pocket between downwardly extending flanges, an inner facing member attached to said meeting rail member and cooperating therewith to secure a pane of glass, and a meeting rail member on the upper sash having a flange adapted to extend into said pocket when the window is closed.

9. In a metal window having an upper and a lower sash, a meeting rail member on the outer face of the lower sash forming the inner wall of a pocket and being then bent outwardly to form the upper wall of said pocket and then upwardly and back upon itself and ending in a. downward extension forming the outer wall of said pocket, an inner facing member attached to said meeting rail member and cooperating therewith to secure a pane of glass, a strip of resilient metal secured to said meeting rail member and having a flange extending into said pocket, and a meeting rail member on the upper sash having a flange adapted to extend into said pocket when the window is closed.

10. In a metal window having an upper and a lower sash, a meeting rail member on the outer face of the. lower sash formed of sheet metal by bending the same back upon itself and then separating the edges to form a pocket between downwardly extending flanges, an inner facing member attached to said meeting rail member and cooperating therewith to secure a pane of glass, a strip of resilient metal secured to said meeting rail member and having a flange extending into said pocket, and a meeting rail member on the upper sash having a flange adapted to extend into said pocket when the window is closed.
